This game is insanely promising! Wow! It is very fun and offers so much! Looks great too :).
My only problem comes with the complexity. Reading through all the powers of each alien is key, yet there are many of them, each with three abilities and its own stats. It's eazy to get lost, hard to move the aliens to a different spot... And this challenging task of finding the best combination comes for each mission - and there are so many missions to do. Sometimes even if you choose a great crew with high chance of winning the RNG comes in, haha xD.
Bug: When you fuse once, you can fuse again to create empty aliens.
This game truly has a lot of potential and I really liked it :)! It's just very hard to deal with all the text. Maybe some other type of indication, a better one for quickly choosing the crew, might make this game a bit less tough. But wow, great job :)!
